The place is very easy to get to by the Airport Rail Link and it is very close to Ratchathewi BTS station.
Note that the elevator doors need to be opened manually.
My room had no windows, which was OK for me since I basically only needed the room to sleep.
The refrigerator had an annoying sound, which I got rid of by turning off the freezer.
You can hear other guests speaking loudly in neighbouring rooms or outside your door but it was not a problem for me because outside sounds do not bother me very much.
The location is very convenient, 5 minute (or even less) walk to Ratchathewi BTS station, only one stop away from Siam BTS station, one stop away from Phaya Thai Airport Rail Link station.
The hosts, Patty and her husband, are very welcoming, attentive and friendly, it was very pleasant to stay at their place.
